See link: You can start the regular birth control right away or wait for your next period and re initiate as "Sunday start". If your period is late or abnormal do a home pregnancy test. Use condoms with any sexual activity to give additional protection against pregnancy and STDs. See link for excellent info from CedarRiver Clinics http://www.birth-control-comparison.info/emergency-contraception-2

Forgetful: Anytime you forget to take a pill,you must use another form of birth control until you finish the pack. If you forget to take a BCP,take it as soon as you remember. If you don,t remember until the next day take 2. If you forget for 2 days-take 2 pills that day and 2 pills the next day-you will then be back on schedule--missed > 2 days call you health care provider for instructions
